What condition of batteries will SmartGauge work reliably with?
This opens up a rather complex question. The question needs to be more clearly defined. Most battery manufacturers and professional users consider a battery to be unserviceable when it’s capacity has fallen to 80% of it’s original capacity. Most people seem to happily use batteries in a much worse condition than this and manage to get useful life out of them. SmartGauge will work reliably with batteries down to 50% of their original capacity. When a battery is in a condition above 50% of it’s original capacity it can simply be regarded as a smaller battery. Below this figure the battery cannot really be considered as tired but more as broken. All sorts of odd things start to happen such as the battery holding acceptable terminal voltage down to about 80% charge status, then suddenly the battery voltage collapses by about 2 volts as one cell gives up the fight. As we said, this can really be considered a faulty or broken battery as opposed to just tired. SmartGauge, like any other type
